Dear Author,

I hope this message finds you well.

I followed your instructions and successfully installed l4casadi. My python version is 3.10 ,visual studio version is 2019,pytroch version is 2.41,cuda version is 11.8 ,windows11.Below is the information confirming the successful installation of l4casadi.

However, when I tried to import l4casadi in PyCharm, I encountered the following error:

Traceback (most recent call last): File "D:\onedrive\Documents\pycharm\pythonProject\CNN_LSTM\hello.py", line 9, in import l4casadi File "D:\programfiles\Anaconda\envs\pytorch\Lib\site-packages\l4casadi__init.py", line 15, in ctypes.CDLL(str(lib_path), mode=ctypes.RTLD_GLOBAL) File "D:\programfiles\Anaconda\envs\pytorch\Lib\ctypes\init.py", line 376, in init__ self._handle = _dlopen(self._name, mode) ^^^^^^^^^^^^^^^^^^^^^^^^^ FileNotFoundError: Could not find module 'D:\programfiles\Anaconda\envs\pytorch\Lib\site-packages\l4casadi\lib\libl4casadi.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I couldn't find the lib\libl4casadi.dll folder and its contents in the system.Below here is the folder screenshot.I would greatly appreciate it if you could advise on how to resolve this issue or let me know if there are any steps I might have overlooked. image

Thank you in advance for your assistance and for all your hard work on this project. Looking forward to your guidance.
